Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Perseid Meteor, Red Sprites, and Nova RS Oph." The title of this image is a mouthful. But if you know where to look, its all there. It would be remarkable to simply capture red sprite lightning, let alone a meteor to go along with it. Toss in a recurrent nova, and that is a moment to remember.
What is a recurrent nova? First, it is not a supernova (the star isn't destroyed). However, if a star is close enough to its white dwarf partner in a binary star system, it is able to feed the white dwarf with its own atmosphere. This newly enriched atmosphere, mostly consisting of hydrogen, is thermally heated by the hot white dwarf and eventually reaches a critical temperature causing ignition of rapid runaway fusion. This is what researchers believe that RS Oph is up to.
Another name for this type of stellar interaction is 'cataclysmic variable star.' Irish amateur Keith Geary was the first to report the surprise outburst of RS Ophiuchi, capturing photos of it glaring at magnitude 5.0 with his DSLR camera at 22:20 UT on August 8th. The last reported recurrent nova was observed with the star V1369 Centauri on December 14, 2013.

Belated thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Monday, August 16, 2021 entitled "Perseid Meteor, Red Sprites, and Nova RS Oph."

APOD Background
"Explanation: This was an unusual sky. It wasn't unusual because of the central band the Milky Way Galaxy, visible along the image left. Most dark skies show part of the Milky Way. It wasn't unusual because of the bright meteor visible on the upper right. Many images taken during last week's Perseid Meteor Shower show meteors, although this Perseid was particularly bright. This sky wasn't unusual because of the red sprites, visible on the lower right. Although this type of lightning has only been noted in the past few decades, images of sprites are becoming more common. This sky wasn't unusual because of the nova, visible just above the image center. Novas bright enough to be seen with the unaided eye occur every few years, with pictured Nova RS Ophiuchus discovered about a week ago. What was most unusual, though, was to capture all these things together, in a single night, on a single sky. The unusual sky occurred above Zacatecas, Mexico."
